7. Citigroup CEO Vikram Pandit quits, stunning Wall Street

NEW YORK -- Vikram Pandit resigned as Citigroup Inc.'s chief executive Tuesday, in a surprise to Wall Street that comes a day after the country's third-largest bank announced stronger-than-expected earnings.

John Havens, Citi's president and chief operating officer, also stepped down Tuesday. The swiftness of the high-level departures fueled speculation about why the executives quit.

Citi's board of directors announced that Michael Corbat has replaced Pandit as CEO and would join the board (Pandit also resigned his board post). Corbat had been Citi's CEO of Europe, the Middle East and Africa.

"Given the progress we have made in the last few years, I have concluded that now is the right time for someone else to take the helm at Citigroup," Pandit said in a statement. "I could not be leaving the company in better hands."
